CAR-COUPLING.

rEPECIFICATION forming part of Letters Patent 'No. 328,931, dated October 27, 1.885.

Application filed September 6, 1884 Serial No. 142,345. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE FORBES, a citizen of the United States, residing at New York city, in the county and State of New York, have invented certain new and useful Improvements in Oar-Couplings; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure l is a longitudinal vertical section of the coupler, having its reserved link stored away and its gravitating coupling-pin D in its normal position ready to be coupledautomatically; Fig. 2, a similar section of the front part, A, of the coupler, having the piece Y partly removed from the slot P; Fig. 3, a perspective View of the piece Y, taken from one of the sides of the slot P; Fig. 4, a plan or top view of the front part, A; Fig. 5, a plan or top View of the bottom of the chamber X of the rear part, A, on the dotted line a: m,- Fig. 6, a rear side View of the loose gravitating coupling-pin D, showing its thickened ends V V; Fig. 7, a view of the end ofa car fitted with theim proved car-coupler and the manual operating device which lifts the crank U; Fig. 8, a longitudinal vertical section of the loose gravitating coupling-pin D, which is made in two parts and riveted together.

Similar letters refer to similar parts throughout the several views.

This invention relates to automatic car-couplings; and it consists in the construction and novel arrangement of the parts, hereinafter fully described.

In the annexed drawings, the letters A A represent the rear and the front parts, respectively, of the draw-head, which are separate and held together by the stationary pin B; X, the chamber for receiving alink, and also for storing the reserved link; 0, two pins; D, the loose gravitating coupling-pin, and B the stationary pin. P in the top part, and T in the bottom part, for the loose gravitating coupling-pin D to fit into, are longitudinal slots; W NV and W WV, fourslots, two laterally of greater width than length, and two longitudinal slots of greator length than width for the stationary pin B to fit into, and which hinges the front part, A, to the rear part, A; E, the elevation; G, the slot in the front part of the elevation E; F, the widened part of the slot G, forming a shelf on which to hang the loose gravitating couplingpin D, by its thickened end .V, up and out of the chamber X; L L, two depressions in the top and the bottom, respectively, of the chamber X; J, the stay, for holding the reserved link 0 out of its draw-head for the purpose of coupling with another draw-head; O, the reserved link; Z, the depression or bed for the reserved link (Jto rest in when it is not wanted for use; H, the passage to allow the rear end of the reserved link 0 to pass into and out of the rear part of the chamber X; 0, the space for holding the rear end of the reserved link 0; J, the stay for holding the reserved link 0 in the rear of the chamber X; U, the crank for lifting the coupling-pin D; h, the rod for working the crank U from the top of the car; Q, the widened part of the slot P, to allow the thickened endVof the loose gravitating coupling-pin Dto be lifted up and out of the chamber X; S, the stay to hold the upper end of the loose gravitating coupling-pin D; R, the stay in the front part of the slot P; a, the depression for the crank U to fit into; Y, the piece to be taken out of the slot 1?, so as to widen it sufficiently to allow the widened end V of the loose gravitating coupling-pin D to be passed through the slot P; T, the rear end of the slot T; VV, the thickened ends of the loose gravitating coupling-pin D; D, the upper piece, and D the lower piece, of theloose gravitating coupling-pin D; d d d, the rivets to hold the two parts of the loose gravitating couplingpin D together, and 0 the binder or covering for protecting the ends of the link 0.

The draw-head is made in two partsA the rear part, and A the front part, respectively. These parts are hinged together by the stationary pin B in such a way that the rear end of A laps over and restson the front end of A. The front end of A and the rear end of A are rounded where they come against each other, for the purpose of allowing A to have plenty of lateral play without having their ends to interfere with that play. The two slots W W are made longer lengthwise, to allow the stationary pin 13 a longitudinal play, but not a lateral play; and the two slots W W" are made longer sidewise to allow the stationary pin B a lateral play, but not a longitudinal play; or this can be reversed by making W W sidewise longer, and W W lengthwise longer. This way of constructing a draw-headgives A sufficient play to allow the link 0, when coupled from the stationary pin B, to be coupled with another draw-head which may be higher or lower than it; also, to allow the link 0 to have enough of play for the up and down and waving motion of the cars when they are in transit; also, to give the link 0 enough of lateral play when the cars are turning round sharp curves.

The chamber X is made with plain'sides, top, and bottom, but having its front part beveled or widened, as shown in Figs. 1 and 2, for the purpose of giving more play to the link. In the bottom part of the chamber X, in A, is a depression to allow the front part of the link 0 to sink, so as to be flush with the bottom of the chamber X, so that the reserve link 0 will not interfere with an enteringlink from another draw-head.

The elevation J is fastened to or molded with the bottom of the chamber X, to help to stop the reserve link Ofrom moving frontward; also, when the chamber X is made without sides to prevent the reserve link 0 from moving sidewise out of the chamber X. The elevation J is fastened to or molded with thetop part of the chamber X,to help hold the reserve link 0 out while it is being coupled with another drawhead. The space 0 is formed by the elevation J and the stationary pin B, for holding the rear end of the reserve link 0. The depressions L L, in the top and bottom of the chamber X, are for giving more vertical play to the reserve link 0 when its rear end is in the space 0. The depression L in the bottom part may be made down to the dotted lines, and if the chamber X is made with sides, then the sides will be made with depressions similar to L L, for giving'more lateral play to the reserve link 0 when its rear end is in the space 0. The passage H is formed by the elevation J and the depression L, and the passage is to allow the rear end of the reserve link 0 to be passed into the rear end of the chamber X.

When the reserve link 0 is to be used for coupling purposes, it is lifted up and out of its bed Z, and in pulling it forward its rear end rides over the elevation J and through the passage H and into the space 0, where it is held out of its draw-head.

The elevation E on the top part of A of the, draw-head in the rear of the slot P is made of such strength, height, and shape to stop the draw-head from being forced too far into its car when an opposite car comes against the draw-head with force. It also has the slot G in its front part, which is widened at F. The slot G is made of such width as to allow the loose gravitating coupling-pin D to fit into it, and where the slot G is widened at F a shelf is formed for the thickened upper end, V, of the loose gravitating coupling-pin D to rest on, for the purpose of holding the coupling pin D up and out of the chamber X. The

loose gravitating coupling-pin D is of a hook or L shape, being constructed in two parts-D the upper part and D the lower part-and are held together by rivets d d d, as shown by Fig. 8, and because the loose gravitatiug couplingpin D is constructed in two parts the lower part, D, is allowed to be passed through the chamber X into the slot P. Then by riveting the upper part, D, to it the loose gravitating coupling-pin D is prevented from being taken from the slot P, whereby it is fixed permanently in the draw-head, and its upper part, D, has a depression, N, in its top part, which. is fitted with a ring or handle for lifting the pin. It is also widened at V, as shown in Fig. 6, for resting on the shelf formed by widening the slot G, at F, and its lower part, D", or shank, has its lower end or edge beveled in such a way as to fit in the groove T in the rear of the slot T, so that when an entering link from another draw-head pushes it inward its beveled edge runs upward and inward in the groove T, and its upper end being lifted rides forward and downward over the block S. Its lower end is thickened and made larger laterally at V, as shown in Fig. 6. This weight V on the end of the pin helps its automatic action, and prevents the pin from being forced out of the slot P; also its lower part, D has on its front edge a slight elevation, as shown in Fig. 8, at 2, which helps to hold the pin in position, as shown in Fig. 1.

The crank U is journaled to the top part of A, having two handles, 6 e, which are shown in Fig. 4, and it fits into the slots and recess u, as shown in Figs. 1, 2, whereby it engages the hook part or shoulder of theloose gravitating couplingpin D, as shown in Figs. 1, 4, and when the crank is turned in the proper direction it raises the pin D out of the chamber X. The crank U can be worked from the top of the car by the manual appliances, as shown in Fig. 7, By turning the handle U in the proper direction, the crank U can be raised, which raises the loose gravitating coupling pin D. The longitudinal slot T is made in the bottom of part A; Its front part is made of sufficient width to allow the thickened end V of the loose gravitating coupling-pin D to fit into it, and its rear part, where it enters the chamber X,is widened'laterally. The outer lower edge of the loose gravitating coupling-pin D rests against the stop or stay 25, formed by the forward verticalv edge of the slot T, as shown by Figs. 1 and 2. The inner edge, T, of the slot '1 is made of such a shape that the lower beveled edge of the loose gravitating coupling pin D is slid upon it and lifted up and inward by it when in the operation of coupling automatically. The longitudinal slot 1? is made in the top of A of sufficient width to allow the upper part of the loose gravitating coupling-pin D to move in it, and its inner part, where it enters the chamber X at Q,is made wider and of sufficient width to allow the thickened end V IIO of the loose gravitating coupling-pin D to fit into it, so as to allow the pin to be raised up and out of the chamber X. The rear end of the slot P is formed by the divergent part a and the vertical part a, which act as stops for the rear edge of the loose graviting couplingpin D. The front part of the slot P is formed by the vertical stop 9, the rest m,which forms the block S, that supportsthe front edge of the coupling-pin D, and the stop B. When the loose gravitating coupling-pin D, as shown in Figs. 1, 6, and 8, is made in one solid piece, having its ends at V V thickened laterally, as shown in Fig. 6, then the movable pieces Yin the sides of the longitudinal slot P, as shown in Fig. 2, are removed so as to give sufficient width to the slot P to allow the thickened end V of the loose gravitating couplingpin D to be put in the draw-head through the slot P,instead of entering the slot P through the chamber X, which can be done when the loose gravitating couplingpin D is made in two parts. \Nhen the pin D is in the slot P,the piecesY are fastened in their places, and thereby prevent the removal of the pin D. The piece Y, as shown in Fig. 3, is made wider at its top than at its bottom, having its rear edge beveled outward two ways and its front edge beveled in the bottom outward, and the upper beveled inward, as shown by yy in Fig. 3. If Y is made thick enough, one movable piece would be sufficient to allow the thickened end V of the loose gravitating coupling-pin D to be put through the longitudinal slot P.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A draw-head made in two parts, A A, so that Aoverlaps A, and the two parts A A are hinged together by the pin B, so as to allow part A play enough for the movements of the reserved link 0 when it is coupled to another draw-head,substantially as described, for the purpose specified.

2. The combinatiomwith the draw-head, of the four slots W'W and NV W, two to be longitudinally of greater length than width and two to be laterally of greater width than length, for the pin B to fit into, for the purpose of giving the part A more play, as and for the purpose described.

3. The combination, with a draw-head, of the elevation E, having the slot G widened at F, which forms a shelf for resting the thickened part V of the loose gravitating couplingpin D for holding the pin in the slots G P up and out of the chamber X, as and for the purpose described.

4. The combination, substantially as hereinbefore set forth, with a draw-head, of the loose gravitating coupling-pin D of hook shape and the retracting-crank U, engaging the hook part of the pin, for the purpose specified.

5. The movable pieces Y in the sides of the longitudinal slot P, for allowing the thickened end V of the loose gravitating coupling-pin D to pass through the slot P, substantially as shown, for the purpose specified.

6. A loose gravitating coupling-pin, D, having its upper part at V slightly thickened laterally for resting on the shelf F, formed in the slot G, and having its lower part at V thickened laterally, which stops the pin from being taken out of the slot P, and the extra weight aids the automatic action, substantially as shown, for the purpose specified.

7. The loose gravitating coupling-pin D, constructed in two parts for the purpose of allowing the lower part to be put into the slot P by Way of the chamber X, and when the lower part is in the slot P, by fastening the upper part to it, the widened ends V and V prevent the loose gravitating coupling-pin D from working out of the slot P, substantially as explained, for the purpose specified.

8. The combination, with a draw-head, of the slot P, the slot T, the loose gravitating coupling-pin D, fitting into the slots 1? T, so that when an entering link pushes against the loose gravitating coupling-pin D the end of the pin slides upward and inward in the groove T, which lifts the loose gravitating couplingpin D and throws its upper end forward and around the stay S, which lifts its lower end in and up out of the chamber X, as and for the purpose specified.

9. A draw-head constructed with the longitudinal slot P, having its inner part at Q widened sufficiently to allow the thickened end V of the loose gravitating coupling-pin D to be in the slot P and up and out of the chamber X, the divergence a and the vertical stop a in its rear end, the stop It and the rest or block S in its front end, the block S forming the rest m, and the vertical stop 9, and having its side at Y movable to allow the thickened end V of the loose gravitating coupling-pin D to be put through the slot P, so that when the loose gravitating coupling-pin D is in its draw-head it cannot work out on account of the thickened end Vand the shape of the slot P, all substantially as set forth.

10. The rod h, journaled to the face of a car, having the arm U on the top and h on its bottom, as and for the purpose described.

11. The combination, in the chamber X, of a draw head with the stay J, the bed Z, and the reserve link 0, as and for the purpose described.

12. The combination, in the chamber X, of draw-head with the stay J, the pin 13, the depressions L L, and similar depressions in the side of the chamber X, and the passage H, as and for the purpose described.
